Hi Jedong, Did you generate the dictionary for FatherClass<double> and MotherClass<double>? Cheers, Philippe -----Original Message----- From: owner-roottalk@pcroot.cern.ch [mailto:owner-roottalk@pcroot.cern.ch]On Behalf Of Jedong Lee Sent: Tuesday, February 25, 2003 9:41 PM To: roottalk@pcroot.cern.ch Subject: [ROOT] Multiple inheritance of templates Hello, Thank you for your previous help. I moved from the version 3.03.07 to 3.05.00, and solved the problem. By the way I have a new problem here. I am trying multiple inheritance: -------------------------------------------------------------------- #ifndef __TestClass__ #define __TestClass__ #include "MotherClass.h" #include "FatherClass.h" template<class Type> class TestClass : public FatherClass<Type>, public MotherClass<Type> { public: TestClass(); ~TestClass(); private: Type *_tree; ClassDefT(TestClass, 1) }; template<class Type> TestClass<Type>::TestClass() { _tree = new Type; } template<class Type> TestClass<Type>::~TestClass() { } #endif ---------------------------------------------------------------------- And I get this message on 3.05.00: ---------------------------------------------------------------------- [jdlee@fcdflnx2 template]$ make all <**compiling**> TestClass.o <**Generating**> TestClass_dict.C <**compiling**> TestClass_dict.o <**linking**> libTest.so Recompiling TestClass_dict.o Warning: Cannot instantiate void MotherClass<T1>::Streamer(TBuffer &) [with T1=double] 1st referenced by TestClass_dict.o Warning: Cannot instantiate void MotherClass<T1>::ShowMembers(TMemberInspector &, char *) [with T1=double] 1st referenced by TestClass_dict.o Warning: Cannot instantiate void FatherClass<T1>::Streamer(TBuffer &) [with T1=double] 1st referenced by TestClass_dict.o Warning: Cannot instantiate void FatherClass<T1>::ShowMembers(TMemberInspector &, char *) [with T1=double] 1st referenced by TestClass_dict.o Warning: Cannot instantiate TClass *MotherClass<T1>::Class() [with T1=double] 1st referenced by TestClass_dict.o <**done**> libTest.so ---------------------------------------------------------------------- .root [0] .L libTest.so dlopen error: /cdf/scratch/jdlee/temp2/template/./libTest.so: undefined symbol: __T_20FatherClass__tm__2_d Load Error: Failed to load Dynamic link library /cdf/scratch/jdlee/temp2/template/./libTest.so *** Interpreter error recovered *** ---------------------------------------------------------------------- However I don't have this problem on 3.03.07. Thank you, Jedong
